status/network: Request scans while wireless menu is open

Browse Source 
We want the list to keep updating, so periodically request scans
from NetworkManager. The code follows what Settings does in its
wifi panel, including the used interval.

There's a cute little spinner in the menu header now, to indicate
an ongoing scan.
